[0002] Fabric is the material used to make clothing. As one of the three elements of clothing, fabric can not only interpret the style and characteristics of clothing, but also directly influence the color and shape of clothing.

[0003] Different fabrics have different properties such as air permeability, moisture absorption, and warmth retention. For example, cotton fabrics have good air permeability and moisture absorption, are comfortable to wear, and have good warmth retention, making them the most ideal fabrics for children's clothing. When choosing fabrics, you should confirm the fabric's air permeability, warmth retention, moisture absorption, static electricity and other performance characteristics, and then consider the fabric's stiffness, weight, softness, hardness, and drape to determine what kind of shape and style it is suitable for.

[0004] In the existing fabric processing work, according to different usage requirements, some fabrics need to be sewn during processing, and this process requires the use of a sewing machine. However, the existing sewing machine requires manual dragging and pulling of the fabric during sewing to ensure the normal transmission and movement of the fabric. It is difficult to ensure a uniform speed during the manual dragging and pulling process. Different speeds will cause differences in the depth and quality of the sewing, thereby affecting the sewing quality of the fabric and reducing the overall processing effect. For this reason, the utility model proposes an automatic sewing machine that can automatically pull the fabric at a uniform speed. Utility Model Content

[0026] See also Figure 1-4 The utility model provides an embodiment: an automatic sewing machine for fabrics, comprising a bottom plate 1, a body base 2 is fixedly installed in the middle of one end of the upper surface of the bottom plate 1, and a sewing machine body 3 is fixedly installed on the upper surface of the body base 2. The sewing machine body 3 is a mature technical product on the existing market, and this specification does not describe its specific structure and working principle;

[0027] A lower protective pad 4 is fixedly installed below the sewing head of the sewing machine body 3 and on the upper surface of the base plate 1. Guide roller mechanisms 5 are fixedly installed on both sides of the lower protective pad 4. The structural dimensions of the two guide roller mechanisms 5 are the same. A winding mechanism 6 is fixedly installed on one side of the outer surface of the base plate 1, and a rewinding mechanism 7 is fixedly installed on the other side of the outer surface of the base plate 1. The winding mechanism 6 and the rewinding mechanism 7 have the same structure, and anti-slip strips 8 are fixedly installed on both sides of the lower surface of the base plate 1.

[0028] In this embodiment, the guide roller mechanism 5 includes a guide roller plate 501, which is fixedly mounted on the upper surface of the bottom plate 1. A concave plate is mounted on the upper surface of the guide roller plate 501, and a lower guide roller 502 is rotatably mounted in the concave plate through a bearing.

[0029] Wherein, side plates 503 are installed at both ends of the lower guide roller 502 and on the upper surface of the guide roller plate 501. The side plates 503 are designed as hollow structures. A screw 504 is rotatably installed in the side plate 503 at one end through a bearing, and a polished rod 505 is fixedly installed in the side plate 503 at the other end.

[0030] Furthermore, the screw rod 504 is externally threadedly connected with a threaded block 506, the outer sliding sleeve of the polished rod 505 is provided with a sliding block 507, and an upper pressing guide roller 508 is rotatably installed between the threaded block 506 and the sliding block 507 via a bearing;

[0031] This structural design, through the guide roller mechanism 5, can provide a guiding and pressing effect when the fabric is pulled, thereby effectively improving the stability of the fabric when it is pulled, and has a better use effect;

[0032] When in use, the fabric is passed through the guide roller mechanisms 5 on both sides, that is, the fabric is placed between the lower guide roller 502 and the upper pressing guide roller 508; thereby, the fabric is tensioned and conveyed through the lower guide roller 502 and the upper pressing guide roller 508, thereby improving the fabric conveying stability;

[0033] Among them, a screw rod 504 is provided at one end of the upper pressing guide roller 508. When the screw rod 504 rotates, the threaded block 506 threadedly connected thereto moves, thereby driving the upper pressing guide roller 508 and the sliding block 507 to move through the up and down linear movement of the threaded block 506, so that the distance between the lower guide roller 502 and the upper pressing guide roller 508 can be effectively adjusted. The technical effect of adjusting the distance can be conveniently adjusted according to the thickness of different fabrics in actual use, so that it can be used for sewing fabrics of different thicknesses, has a good thickness application range, effectively reduces the use limitations of the device, and has a good use effect;

[0034] At the same time, the spacing adjustment method can also adjust the clamping force between the lower guide roller 502 and the upper pressure guide roller 508. When the spacing between the lower guide roller 502 and the upper pressure guide roller 508 is small, the clamping force is large. On the contrary, when the spacing between the lower guide roller 502 and the upper pressure guide roller 508 is large, the clamping force becomes smaller. This can be used for conveying fabrics of different toughness, with good performance. A single technical solution can achieve dual practical effects and has good practicality.

[0035] Furthermore, in order to facilitate manual adjustment of the height of the upper pressing guide roller 508 , an adjustment knob 509 is fixedly connected to the top of the screw rod 504 , and an anti-slip serration is arranged on the outside of the adjustment knob 509 .

[0036] In this embodiment, the winding mechanism 6 includes a side mounting plate 601, which is fixedly mounted on the side wall of the bottom plate 1, and fixed brackets 602 are fixedly mounted on both sides of the outer surface of the side mounting plate 601, and the fixed brackets 602 are arranged in an "L"-shaped structure;

[0037] Furthermore, a winding roller 603 is rotatably installed between the two fixed brackets 602 via a rotating shaft, and one end of the central axis of the winding roller 603 is fixedly connected to the output shaft of a servo motor 604, and the servo motor 604 is fixedly installed on the outer wall of the fixed bracket 602 on one side;

[0038] This structural design can be carried out by the set servo motor 604 to rotate at a uniform speed, so that the uniform rotation of the servo motor 604 can drive the winding roller 603 to rotate at a uniform speed, so that the fabric can be effectively rolled up and pulled laterally by the winding roller 603 that rotates at a uniform speed, thereby ensuring the uniform speed transmission of the sewing fabric. In actual use, the uniform speed transmission speed of the fabric in the whole process of sewing can be effectively guaranteed. Compared with manual traction and pulling of the fabric, the utility model can effectively ensure the uniform speed effect of the fabric transmission through automatic uniform speed winding, avoid the influence of different speeds on the sewing quality, effectively improve the sewing quality of the fabric, and increase the overall processing effect of the fabric.

[0039] Working principle: When in use, the fabric to be sewn is first rolled up on the unwinding mechanism 7, and then one end of the fabric is passed through the two guide roller mechanisms 5 and fixed on the winding roller 603 of the winding mechanism 6;

[0040] It should be noted that when the fabric passes through the two guide roller mechanisms 5, the upper and lower outer surfaces of the fabric need to contact the upper and lower rollers of the guide roller mechanism to ensure the normal use of the guide roller mechanism 5;

[0041] At this time, the sewing machine body 3 is working to sew the fabric, and at the same time, the servo motors of the unwinding mechanism 7 and the rewinding mechanism 6 are rotating, the unwinding mechanism 7 unwinds the fabric, and the rewinding mechanism 6 rewinds the fabric, so as to ensure the normal transmission of the fabric;

[0042] The servo motor 604 can rotate at a uniform speed, so that the uniform rotation of the servo motor 604 drives the winding roller 603 to rotate at a uniform speed, so that the winding roller 603 that rotates at a uniform speed can effectively roll up and pull the fabric sideways, thereby ensuring the uniform transmission of the sewing fabric. In actual use, the uniform transmission speed of the fabric in the whole process of sewing can be effectively guaranteed. Compared with manual traction and pulling of the fabric, the utility model can effectively ensure the uniform transmission effect of the fabric through automatic uniform winding, avoid the influence of different speeds on the sewing quality, effectively improve the sewing quality of the fabric, and increase the overall processing effect of the fabric.

[0043] At the same time, the utility model can provide a guiding and pressing effect when the fabric is pulled by the guide roller mechanism 5, thereby effectively improving the stability of the fabric when it is pulled, and has a better use effect;

[0044] When in use, the fabric is passed through the guide roller mechanisms 5 on both sides, that is, the fabric is placed between the lower guide roller 502 and the upper pressing guide roller 508; thereby, the fabric is tensioned and conveyed through the lower guide roller 502 and the upper pressing guide roller 508, thereby improving the fabric conveying stability;

[0045] Among them, a screw rod 504 is provided at one end of the upper pressing guide roller 508. When the screw rod 504 rotates, the threaded block 506 threadedly connected thereto moves, thereby driving the upper pressing guide roller 508 and the sliding block 507 to move through the up and down linear movement of the threaded block 506, so that the distance between the lower guide roller 502 and the upper pressing guide roller 508 can be effectively adjusted. The technical effect of adjusting the distance can be conveniently adjusted according to the thickness of different fabrics in actual use, so that it can be used for sewing fabrics of different thicknesses, has a good thickness application range, effectively reduces the use limitations of the device, and has a good use effect;

[0046] At the same time, the spacing adjustment method can also adjust the clamping force between the lower guide roller 502 and the upper pressure guide roller 508. When the spacing between the lower guide roller 502 and the upper pressure guide roller 508 is small, the clamping force is large. On the contrary, when the spacing between the lower guide roller 502 and the upper pressure guide roller 508 is large, the clamping force becomes smaller. This can be used for conveying fabrics of different toughness, with good performance. A single technical solution can achieve dual practical effects and has good practicality.
